An ongoing maintenance and safety project to remove and replace signs that span highways will result in overnight lane closures on metro-area roads, according to the Colorado Department of Transportation.

The $567,000 project, which aims to be wrapped up by late June, will involve removing, replacing and installing more than 500 signs over highways including Interstates 25, 70, 76, 225 and 270; U.S. 6, 36 and 285; Colorado 58 and 287; and C-470, CDOT said in a news release.

On Monday night the project will result in a full ramp closure from northbound I-25 toward I-225 from 11 p.m. to 5 a.m. Northbound I-25 traffic will detour at the Hampden exit to access northbound I-225. The southbound I-25 ramp to access northbound I-225 will remain open.

On Thursday night all lanes of westbound I-70 west of Wadsworth Boulevard are scheduled to be closed, along with a single left-lane closure on eastbound I-70. All lanes in both directions will open by 5 a.m., CDOT said. Multiple detours will be posted.

Future closures will be announced. The overnight lane closures are required to ensure the safety of motorists and crews during the project, CDOT said.

CDOT is working with Paonia Inc., the contractor, on completion of the project. The new signs will benefit the traveling public by providing improved communications on safety, rules and road conditions.
